I had a disc removed from my lumbar spine about five years ago. The doctor says it has filled in with scar tissue. That's what's causing the return of my pain. Is it worth it to have another operation to remove the scar tissue? I guess it's wrapped around the nerve, and that's what's causing all the trouble.

Scientists have yet to unravel the mystery of scar tissue. Some people form lots and lots while others not enough. Too much scar tissue (as you have found out) can put pressure on the nearby tissues causing painful symptoms.

When the nerve is involved, nerve pain, numbness, tingling, and other symptoms of nerve involvement can become major problems. Removing scar tissue in a person whose body forms excess scar tissue may not be an acceptable solution to the problem.

In recent years, new research has been testing out the use of gels and fat grafts to prevent scar tissue formation. The early results have been very successful. But long-term results are very limited at this point in time.
